⚡ At a Glance
- • Durability: High-grade engineered rubber combined with the ribbed profile resists wear and cracking
- • Best for: Light-duty transmission systems, DIY workshop maintenance and small appliance repairs
- • Not ideal for: High-torque industrial drives or heavy-load machinery
Pack contains five 135J belts with a 343mm circumference, metric code PJ343. Multiple V-ribbed profile provides friction and wedge advantages for reliable belt engagement.
Consistent power transfer - with multiple V-ribbed profile
The V-ribbed profile increases contact surface and creates wedge action under tension, improving grip on pulley flanges. The profile is described as providing friction and wedge advantages in the product details.
More secure engagement reduces slippage and helps keep rotational speed steady during operation.
Long service life - with high-grade engineered rubber
Engineered rubber formulation resists folding fatigue and surface wear across repeated bending cycles. The material choice is stated explicitly in the product description.
Fewer unexpected failures and longer intervals between replacements, making maintenance schedules easier to plan.
Straightforward sizing and selection - with PJ343 (135J) and clear rib codes
The 135J series is linked to a 343mm circumference under the metric code PJ343, while J4, J5 and similar labels denote the number of ribs. The description clarifies rib-count labelling.
Quick identification of the correct belt for a pulley saves time during repairs and reduces the chance of fitting the wrong item.
